This is a functional fix for polygon parsing; the bug that is addressed by the fix is that polygons with > 1000 lines take a long time to parse.
This is because the loop goes through the polygon parsing for each coordinate entry: this is unnecessary and degrades performance a lot: more coordinates results in more unnecessary loops.
The fix cuts the loop for polygons after the first parsing.
Of course, this is a sort of a hack ... the correct way to fix this would be to follow the top-down structure of the kml instead of looping directly over all coordinates, just to go back to the parent, parse the parent and then do it all over again ...
